CARRIER.

To all whom it may concern:

Be it known that I, CLEMENS B. WILLnN- none, a citizen of the United States, residing at Dyersville, in the county of Dubuque and State of Iowa, have invented a new and useful Carrier, of which the following is a specification. v I

This invention has relation to carriers and it consists in the novel construction and arrangement of its parts as hereinafter shown and described. 4

The object of the invention is to provide a carrier adapted to travel u on a suspended or overhead cable and Whic is so mounted upon its supporting wheels that the liability 0 disconnecting the carrierfrom the sup porting cable when the said carrier is given a sudden push is reduced to a minimum.

. NVith the above objects in view the carrier ncludes a bucket pivotally attached to the end of a bail. One wheel is freely castered to the upper portion of the bail and another supporting wheel iscastcred for limited movement with relation to the bail and is jonrnaled upon an arm pivoted for vertical swing.

In the accompanying drawings; Figure 1 is a side elevation ofthe carrier. Fig. 2 is an end elevation of the same showing the bucket in dumping position. Fig. 3 is a vertical sectional view of a )ortion of the carrier cut on the line 3-3 of Fig. 1. Fig. 4 is a vertical sectional view of a portion of the carrier cut on the line 44 of Fig. 1. Fig. 5 is a horizontal sectional view of aportion of the carrier cut on the line 5-4) of Fig. 3. I

The carrier consists of a bucket '1 which is pivoted at each end to the extremities of a U shaped bail 2. A disk 3 is mounted upon one end of the bucket l and is provided on its periphery with a slot 4. pin 5 is located upon the outer face of the disk 3. and the lmver port ion of the adjacent end of the bail 3. is in the path of movement of the pin 5 when the bucket assumes a dumping position.

As illustrated in Fig. 2 of the drawings, one end ol the bail 2 may be provided with )erloration (i whichat times is adapted to ister with a perforation 7 provided in the c 3. Vixen the said perforzflioyrs are in icmcnt with each other the bucket l is in :iving position and by inserting a pin or who! securing device (not shown) through Specification of Letters Patent.

may be held in positive or fixed relation to the bail 2. Guides 8 are carried by one end of the bail 2 and a rod 9 is slidably mounted in the said guides. The rod 9 carries at its lower end a awl or pin which is ada ted to enter the S t 1 provided in the perip iery of the disk 3 and hold the bucket 1 in fixed v A coil spring 11 surrounds the rod'i) and bears at one end against the upper guide 8 and at its lower end against a collar 12 fixed to the said rod 9. The spring 11- is under tension with a tendency to hold the rod 9 in a depressed position in the guides 8. yoke 13 is pivotally connected with the upper end of the rod 1) and projects beyond the upper intermediate portion of the bail 2.

A lever 1 1 is positioned u on the upper intermediate portion of the ail 2 and its working end is pivotally connected with the upper end of the yoke 13. The bail l4: lies under a supporting cable 15 which is held suspended by any suitable means. A Wheeled frame 16 is pivoted to the upper intermediate portion of the bail 2 and carries a grooved wheel 17 and hence the said wheel is referred to as being freely castered; The said wheel 17 is adapted to travel upon the cable 15. A frame 18 is pivoted for limited pivotal movement at the upper intermediate portion of the bail 2 and an arm 19 is pivoted in the frame 18 and isconiined to a limited vertical swingin movement. A rooved wheel 20 is journale at the forwar end of the arm 19 and is also adapted to travel.

upon the-cable 15. Therefore the arm 19 and wheel 20 constitute a caster structure having limited castered movement. The arm 19 is pivoted upon a in 21 which extends transversely across tie frame 18 a d the said arm and the vertical swinging movement of the said arm is limited by a cross pin- 22 which extends transversely across the frame 18 and lies below the pin 21 in the path of movement of the opposite end portion of the arm 19 11' that end thereof to which the wheel 20 is ournaled.

Any suitable means may be employed for limiting the castered movementof the frame is and as illustrated in Figs. 3 and 5 of the drawings such means consists of a pin 23 which is secured at its ends to the fixed porlions ot' the bearing 24 upon which the frame 14s mounted and at its intermediate portion is slightly spaced from a perfora lion passing trans\"ersely through the shank of the frame 18. By this arrangement it will be seen that the said frame 18 has limited castered movement with relation to the bearing 2&.

From the above description it is obvious that when the carrier is placed upon a supporting cable as indicated and is su 'qected to a sudden shove to move the same along the cable and aslhe shove is applied to that enu thereof opposite the end over which the wheel 20 is located that should there be a tendency to lift the forward end of the bucket or carrier then the wheel 20 may be permitted to remain at the same level that is to say upon the upper surface of the cable 15 and is not compelled to follow the forward end of the carrier in its upward movement. Thus the possibility of detaching or derailing the wheel 20 from the cable track 15 is reduced to a minimum for as soon as the push is delivered the forward end of the carrier will descend by gravity and the parts will assume their proper normal condition.

lnasnmch as the frame 18- is al'owed to have limited caster movement only there is sufficient movement on the part of the said frame to permit the wheel Qt) to follow a curved cable track 15 without jumping from the same but at the same ime the movement of the frame 18 is not sullicient to permitthe .vheel 20 to swing laterally away from the cable or track 15 when the carrier is given a sudden push as indicated. By reason. of the fact that the frame 10 is freely castered it is at liberty to follow along the course or track of the cable 15.

The carrier herein shown and described may be used in connection with any suitable form of stop or depressor attached to the cable 15 and as the carrier passes along this cable the power end of the lever 14' may be carried under such a depressor whereby the said lever is formed upon its fulcrum and the rod 9 is moved longitudinally. Such movement on the part: of the rod 19 disengages the end. from the slot 1 in the periphcry of the disk 3 and the bucket 1 is free to turn laterally and assume a dumping position in a manner usually employed in devices of this character.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A carrier comprising a bucket and a bail, a supporting wheel located at one end of the bail, and being relatively fixed vertically with relation to the same and a supporting wheel located at the other end of the bail and being free for limited vertical movement with relation to the bail.

2. A carrier comprising a bucket and a bail, a caster wheel located at one end of the bail and being relatively fixed in a vertical direction with relation to the bail a caster wheel located at the other end of the bail and having limited vertical swinging m ven'ient with relation to the bail.

3. A carrier comprising a bucket and a bail, a caster wheel located at one end of the bail and being relatively fixed vertically with relation [0 the same, a frame mounted for limited caster-ed movement at the other I end of the bail, an arm mounted for limited vertical swinging in the last said frame and a sup iiorting wheel jourualed for rotation in the said arm.

4. A carrier comprising a bail, a bucket pivotally mounted in the bail, a disk attached to the bucket, and having in its periphery a slot, a pin located upon the outer face of the disk and adapted to engage the side of the bail when the bucket assumes dumping position, and supporting wheels for the bail.

l 11 testimony that I claim the foregoing as my owm 1 have hereto aflixed my signa- (Inc in the presence of two witnesses.
